Letters to the Editors, June/July 2006

"Each time you think you are unveiling the truth, all you get is a teasing glimpse of what turns out to be yet another veil," wrote Vilayanur S. Ramachandran and Diane Rogers-Ramachandran in their February/March Illusions column ["Stability of the Visual World"]. Their words eloquently capture the stubborn persistence of researchers as they grapple with seemingly impenetrable mysteries of the mind.

Along the same lines, articles in the issue discussed the struggle to understand how mental imagery forms ["Picture This," by Thomas Grueter], how sexuality can vary ["Do Gays Have a Choice?" by Robert Epstein], whether our fellow creatures emote ["Do Animals Have Feelings?" by Klaus Wilhelm] and more.
